Signed out of Xbox Live, disconnect/reconnect to wireless and it works again. Why?

So, occasionaly I'll be playing on Xbox Live, any game. And I'll randomly get disconnected from Xbox Live. But when I check my network, my NAT type is Open, and everythings seems fine. Then I disconnect from my wifi, and immediately re-connect to it, and
wahlah, I'm magically connected to XBL again. Why? Can someone explain this to me? Why am I being disconnected from XBL, if when I disconnect my wifi, and reconnect back to it again, it immediately lets me get back online? It makes no sense. Then, there's
a lot of times I'll check my network connection before I disconnect from the wifi, and it says I have no internet access, but if I discoonnect and reconnect it's imediately working again. I'm confused.

Xbox One disconnecting from Internet need help

I had the same issue recently. My controller was also frequently disconnecting and then failing to reconnect. Disabling 'Instant On' has seemingly fixed my wireless problems.

 

strange connection troubles

I'm having a strange problem ; when I connect my Xbox 360 to Xbox live but I do not sign in it will connect normally, but when I sign in it will disconnect and I cannot reconnect as long as I am signed in. When I sign out again it reconnects to Xbox live
again. My other console connects to the internet normally. is it a problem with my 360?

 

It may be an issue with either the modem/router or your internet. Try unplugging the modem/router for 5 seconds to see if that helps. You may also want to contact your internet service provider to ask about it.
